This paper describes an Interactive Shared Journal System (ISJS) that provides access, support, and sharing for the processes of learning to become a teacher. This system is a component of the undergraduate teacher education program at the University of Missouri-Columbia. ISJS is a flexible system for the development and support of learning communities, but in the context of the undergraduate teacher development program it can best be understood as enabling three key processes--access to Internet-based resources, capturing experiences, and sharing experiences. These processes are undertaken in the context of a community made up of four roles: administrators, who are responsible for the system; mentors, who are responsible for instruction and modeling; students, who are responsible for articulation of experiences; and guests, who have limited access to public information. Topics discussed include: technology infrastructure; access to resources; the organization and use of the journal system; and sharing experiences using an archive, live chat, and instructor-structured experiences distributed to individual students or to groups. Results of the pilot year of implementation and future plans are also covered. Four figures illustrate: the tools window; a list of journal entries; a sample journal entry showing text, links, an image, and a sound; and a system user profile window. (DLS)
